Julias frogs are 2/5 of the amount of Remus frogs. If Remus gives a half of his frogs to Julia, what will the ratio of Julia's frogs to Remus frogs be ?

Respuesta :

Let:

Rf = Remus frogs

Jf = Julias frogs

[tex]Jf=\frac{2}{5}Rf[/tex]

If Remus gives a half of his frogs to Julia, what will the ratio of Julia's frogs to Remus frogs be ? so:

[tex]\begin{gathered} Rf=\frac{5}{2}Jf \\ Jf=\frac{2}{5}Rf+\frac{1}{2}Rf=\frac{9}{10}Rf \end{gathered}[/tex]

Therefore, the ratio will be:

[tex]\frac{\frac{9}{10}Rf}{Rf-\frac{1}{2}Rf}=\frac{9}{5}[/tex]
